Patent DK-5685-A (DK)
Inventor: SEELIG RENATE
IPC: C12N7/02
Filed: 1985-01-04
Abstract: The invention relates to a process for obtaining a virus, respectively a virus antigen from biological material, particularly from body liquids, whereby fibronectine to which the virus is bound is extracted; to this effect, as a starting material will be used either a body liquid containing already fibronectine or a biological starting material to which fibronectine has been previously added; after isolating the fibronectine to which the virus is bound, the virus, respectively the viral antigen is obtained in a free state by breakage of the bond with the fibronectine; this release of the virus may be carried out according to a known process, particularly by specific enzyme action and/or surfactant action or by elimination reactions or simply by heating; as a result, a suspension is obtained from which the virus respectively the viral antigen may be isolated; the latter may be further purified in a manner known per se. The virus, respectively the viral antigen thus obtained, - and this concerns particularly the virus of hepatitis non A-non B -, is one aspect of the invention; however, the field of the invention extends also to the utilisation of the viral antigen obtained for the preparation of corresponding antibodies, to the field of immunologic diagnostic of hepatitis non A-non B and to the field of the preparation of vaccines. Furthermore, the invention also relates to a diagnostic kit enabling to diagnose the virus, respectively the viral antigenic material masked by the presence of unbroken or broken up fibronectine.

Abstract: 649,573. Phase difference measuring. RAYTHEON MANUFACTURING CO. Jan. 1, 1946, No. 48. Convention date. Jan. 17, 1945. [Class 37] [Also in Group XXXVIII] In a system for measuring the velocity of a body relative to a surrounding fluid medium as a function of the velocity of compressional waves in the medium (see Group XXXVIII), the phase difference #1 of two electrical oscillations of equal frequency is determined by applying them respectively through transformers 30 and 31 to valves 34 and 35 which are directly coupled respectively to the grid and cathode of valve 43. Valves 34 and 35 are biassed to cut off and valve 43 is biassed so that it is only conductive when valve 34 is cut off and valve 35 is conductive thus producing a current pulse of duration proportional to the phase difference #1, Fig. 8 (not shown).

Abstract: 851,805. Mounting electrical equipment. COLLINS RADIO CO. Jan. 1, 1959 [May 19, 1958], No. 92/59. Class 37 A mechanical valve for controlling the flow of cooling fluid to an individual chassis of a rack of equipment comprises a disc and a secondary duct mounted on a main duct, such that the disc is urged against the main duct and prevents fluid flow through the secondary duct when the chassis is withdrawn. Pressure of a mounted chassis against a plunger connected to the disc moves it inwards to allow fluid flow through the secondary duct, the end of which is made resilient to press tightly against the chassis and provide a fluid tight joint. As shown, a secondary duct 18 of resilient material, e.g. rubber or neoprene has groove at one end by which it is mounted grommet fashion through a hole in the main duct 13. The other end of the duct 18 has a resilient lip 21 which forms the fluid tight joint with the chassis 14. A hollow plunger 15 is mounted inside the duct 18 and is urged inwards by pressure against the wall of the chassis to hold the disc 11 away from the wall of the duct 13. The disc is urged towards the wall by the spring 22, so that removal of the chassis allows the disc to close against the seating 20. The chassis 14 may be mounted on a rack 24 by means of'the hinge 25 and screw 26.

Abstract: 997,021. Air cushion vehicles; tipping trailers. E. C. KENNEDY, and J. W. PATTISON. April 2, 1964 [Jan. 2, 1963], No. 241/63. Headings B7B and B7K. An air cushion vehicle, e.g. a tipping trailer, has ground engaging wheels 1 or runners mounted on a chassis C and a flexible skirt 13 and means for venting the cushion to atmosphere to prevent the wheels or runners being lifted from the ground. The vehicle also comprises a frame F hinged to the chassis at its front by pivots 9 and aligned by rollers 31 (Fig. 4) at the rear, and a body B which can be tipped about pivots 26 by a hydraulic ram 28 or by manually operated raising gear. A fan 19 is mounted on the frame, and discharges air through an opening 18 in a metal floor 15 of the frame. The air cushion pressure therefore acts on the frame to raise it and reduce the load on the wheels or runners. In one embodiment (Figs. 3 and 4) the skirt 13 is mounted on the frame so that if the latter is raised beyond a predetermined amount, the skirt leaves the ground and the air cushion pressure is reduced. Wheels 1 are fitted within the cushion on plates 4 (Fig. 3) pivotable about a tube 5 by hydraulic rams 6 so that the wheels may be raised for replacement or servicing, doors in the frame structure facilitating access. In another embodiment (Fig. 7) the skirt 13a is fixed to the chassis and a sealing strip 32 which normally seals a gap between the frame and a chassis member is lifted by a rod 34 having an abutment 35 which engages a channel member 7a on the frame. When the strip is lifted, air is vented from the cushions through an opening 36, reducing the cushion pressure. Wheels are provided externally of the cushion (Fig. 6, not shown). The fan is driven by power offtake from a tractor, as shown, or by its own driving motor. Alternatively the fan may be external of the body, air being ducted from it to the cushion.

Filed: 1943-01-14
Abstract: 563,534. Absorption dynamometers. GARRETT, F. A. Jan. 14, 1943, No. 731. [Class 106 (ii)] A dynamometer of the prony brake type bas two levers 7, 8 which are fulcrumed together, are connected at one side of the fulcra 18, to brake shoes 3, 4 on a brake drum 1, and have resilient means for applying load to them at the other side of the fulcra so as to apply the brake shoes to the drum, the brake shoes having adjustable abutments 12, 15 for engagement with the levers so that the levers act alternatively as brake levers or secondary levers according to the direction of rotation of the drum and actuate reaction means adapted to indicate the torque load. In the embodiment shown in Fig. 1, a screw 23 is adjusted until the brake shoes are applied to the drum, and screws 12, 15 are set slightly clear of the levers 7, 8. According to the sense of rotation of the drum, one or other of the screws 12,15 engages its corresponding lever which drives the other lever into contact with the torque indicator 26 or 27. Momentary variations of the load are absorbed by a spring 21. In Fig. 2, the spring 21 is replaced by a pair of hydraulic cylinders 30 connected to a loading cylinder and a pressure gauge. The force of the brake lever is absorbed by one or other of two hydraulic cylinders 59, 60, connected together to a loading cylinder and to a pressure gauge which indicates the torque. The levers 7, 8 and the brake shoes are counterbalanced by weights 86, 87. The pressure in the hydraulic cylinders can be released by a manually operated ball valve connecting the loading cylinders with a reservoir. In Fig. 8, the cylinders 59, 60 are replaced by a single cylinder 101, movement of the levers 7, 8 being transmitted through a cable 113 to one or other of two bell-cranks 109, 110 adjustable by screws 122, 123 on a lever 107 centrally pivoted to the plunger 104. The lever 107 turns about one or other of two rollers 124, 125 abutting against the frame, to transmit pressure to the cylinder 103. The brake drum, Fig. 7, is hollow and receives cooling water from a pipe 81, the water escaping through a trough 82.

Abstract: 389,604. Testing flour &c. STERNGES. FœR MODERNE GRUNDBAUTECHNIK, 8, Schenkenstrasse, Vienna Jan. 11, 1932, No. 791. Convention date; Jan. 13, 1931. [Class 58.] Relates to a method for mechanically deter. mining the fineness of loose aggregates, foi example, broken up or ground coal, stone and ores, or agricultural products such as flour, grits, and groats which are to be subsequently treated. In dealing with aggregates for con. crete, a definite quantity of the material i, passed through a set of sieves graded in a geometrical series and the residues in the sieve, are suspended in scale pans 5 from one arm o: a scale beam 2 at leverage arms proportional tc the fineness moduli of the individual residues, and a balance is effected by a sliding poise 9 equal in weight to the total test quantity of material. The fineness modulus of the material is indicated on a scale 11. The Specification as open to inspection under Sect. 91 comprises also a method wherein the aggregate is divided into a number of equal parts which are placed in a sifting frame, Fig. 4 (Cancelled), divided into the sieves of various mesh. A similarly-meshed cover is added and the frame is rocked on its pins 14 to sift the portions, the fineness modulus being calculated from the weights of the residues. In a modified weighing device, a platform machine is used and the residue-containing sieves are caused to act on the platform by means of intermediate levers of appropriate leverages. In a further modification, Fig. 7 (Cancelled), the residue of the largest sieve 28 is weighed alone by adjusting a poise 22, the movement being transferred by a rack and pawl mechanism to a pointer 27. The poise is returned to zero (leaving the pointer undisturbed) and a frame 33 is lowered to place both the sieves 29, 28 on the weighing machine. The poise is again moved to balancing point and a corresponding addition is thus given to the pointer reading. The operation is repeated as the sieves are added successively, and the final reading of the pointer gives the fineness modulus. An assembly of apparatus, including a drying drum and a volumenometer, is also described for ascertaining the quantity of moisture in the aggregate and sifting the dried aggregate through the series of sieves prior to ascertaining the fineness modulus by means of the balance first described above. This subject-matter does not appear in the Specification as accepted.
